TENSION AND SUPPORTING MEMBER FOR CONCRETE CONSTRUCTION.

Specification of Letters Patent.

Patented Aug. 2 5, 1908.

Application filed October 3, 1906. Serial No. 337,166.

To all whom at may concern.

Be it known that I, J ULIUS TUTEUR, a citizen of the United States ofAmerica, and a resident of Cleveland, in the county of Cuya- 5 hoga andState of Ohio, have invented certain new and useful Improvements inTension and Supporting Members for Concrete Construction, of which thefollowing is a specification.

My invention relates to improvements in tension and supporting membersfor concrete construction, and has for its object, the provision ofmeans for strengthening such construction in the easiest and mostefficient manner. The necessity of providing throughout structuralmembers of concrete, sufiicient steel or iron to take up the tensilestrain, is now well recognized. Doubtless, the best method ofaccomplishing this, lies in providing upon the principal steelstructural member, numerous reinforcing parts or members angularlydisposed with respect thereto, approximating the line of principaltensile stress; this composite member of course being completelyembedded. in the concrete.

The practical embodiment of the foregoing structure now made use of inpractice, comprises a rolled bar of appropriate cross section withrelatively wide webs upon either side thereof. These webs are shearedfrom the bar at intervals, and bent at an appropriate angle therewith,to insure the proper anchorage, and carry the stress or strain from theadjacent concrete into the bar, or to the tension-member or chord thusformed. While this structure has its own advantages, it will beunderstood that the angular members thereof are strictly limited innumber, length and cross section by the web portion of the bar, and myinvention has proceeded with the thought of providing means where by theangularly extending members may be adjusted in position upon the bar asdesired, both as to the number, length and location thereof.

Briefly describing an embodiment of my invention, I may say that itcomprises a bar or rod of any suitable cross section, whereon are keyedor properly secured anchorage members formed of castings suitably shapedto receive metal straps bent at an angle with the bar, to form shearmembers or angularly disposed stays extending into the body of theconcrete.

5 Several modifications of my improvements are shown in the annexeddrawings, in connection with which I shall now further explain myinvention, wherein Figures I to IV. are perspective views of blocks orcastings of different types adapted to be used as anchorage members.Fig. V. is a cross section of one of said castings. Fig. VI. illustratestwo of such members as the same are positioned for use upon a bar or rodwhich is broken away. Fig. VII. illustrates another of said blocksmounted upon a twisted rod, and with the stay-members differentlypositioned and bent. Fig. VIII. is a plan view of still another block,with the stay-member circularly bent for use in columnar structures.Figs. IX and X. show keys; and, Fig. XI. depicts one of the completestructures equipped, and in use.

Throughout each of the several figures, the same character of referencehas been employed to indicate similar parts.

In considering the foregoing drawings, moreover, it should be understoodthat no full or detailed illustration or description can be given inthis brief specification of the many types and applications of myinvention, but I have endeavored to set forth typical examples thereofin a manner enabling any one to practice the same.

Referring first to Fig. XI. it will be seen that a baror rod a of roundcross section, for example, is embedded within the concrete beam a, andupon it at intervals are positioned the castings c, with their shearmembers angularly bent or inclined to the vertical, in order toapproximate the line of rincipal tensile stress therein. As is welunderstood, the mass of concrete itself is amply able to take care ofthe compressional strain, while the adhesion of the numerous shearmembers and anchors or castings,- transmits directly to the chord or barmuch of the ten sile stress sustained by the entire structure.Accordingly, an arching or truss-like action is present, insuringmaximum strength.

Considering now the other figures, I may explain the features of myinvention more in detail. The first figures of the drawings showdifferent types of castings c, which are longitudinally recessed at d,to accommodate bars of different cross section. A transversely extendingopening or openings e are. likewise provided for the reception of metalstraps b, which are securely held within the casting, and may beibenttoiextend at the proper angle into the concrete, as shown in igs. VI toVIII. These castings or anchorage blocks may be placed in position uponthe rods as closely together as are required, and during the progress ofthe work, being securely keyed thereon by means of ap ropriate keys f,g, inserted within the myways f g. It will be understood, of course,that the dimensions of all these members may thus be readily conformedto the nature and character of the work under way, and particularly thatthe shear members or an gularly extending straps b are capable of beingreadily placed in any desired position, and being made lighter orheavier, and longer or shorter, as is required.

Further modifications could readily be set forth herein, but inasmuchas, my invention does not concern itself with the details such as wouldnecessarily be involved, or are herein set forth, I may conclude thisexplanation with the statement that I desire to reserve to myself allsuch modifications as may consist i111 ppange of form or require onlymechanical s 1 I therefore claim the following i 1. In a structure ofthe class described, the

combination with a metal bar or rod, of a plurality of anchorage-blockssecured at intervals thereto, said blocks being respectively providedwith transverse openings, and metal straps extending through saidopenings and bent at an angle with the bar or rod to form supports orstays, substantially as set forth.

2. In a tension and supporting member for concrete construction, thecombination with a rod or bar, of a plurality of blocks or castingssecured at intervals thereto, each being equipped with transverseopenings, and metal straps extending through said openings and bent atan angle with the rod and block to form stays or supports adapted totransmit tensile stress thereto, substantially as set forth.

3. A universal tension member for concrete construction, comprising arod of substantially uniform cross-section, a plurality of adjustableanchorage-blocks positioned thereon; the same consisting of a metalliccasting having a longitudinal bore and transverse openings angularlydisposed with respect to each other, keys respectively securing theblocks in place upon the rod, and shear members extending through thetransverse openings in the blocks and bent at an angle therewith andwith said rod, to lie within the concrete structure, substantially asset forth.

4. In a concrete structure, the combination with the body of concrete,of a tension member embedded near the lower portion thereof comprising ametal rod, castings secured to said rod and equipped with transverseopenings, and metal straps retained within the openings in said castingsand bent at angles inclined to the vertical approximating the lines ofprincipal tensile stress, substantially as set forth.

5. A universal tension member for concrete construction, comprising arod of substantially uniform cross section, and a plurality ofadjustable blocks or castings embracing said rod and advantageouslysecured along said rod in position'to take up tensile stress from theconcrete the same having transverse passages or openings, and shearmembers inserted within said passages in the blocks and adapted toextend within the body of concrete, substantially as set forth.

6. In an anchorage-block for concrete tension members, the combinationwith a casting having a longitudinal bore to receive the tension-rod,and a key-way, of transverse combination with the body of concrete, of atension rod of substantially uniform crosssection embedded therein,anchorage blocks thereon, said anchorage blocks having longitudinalbores for engaging the rod, and transverse passages or receptacles, keysrespectively securing the blocks in any desired po sition upon the rod,and metal straps inserted within said transverse receptacles in theblocks, bent to extend at an angle approximating the lines of principalstress in the Ibody of the concrete, substantially as set fort 9. In atension member for concrete construction, the combination with a rodhaving substantially uniform cross-section, of a plurality of anchorageblocks positioned thereon the same comprising relatively massivecastings having a longitudinal bore substantially the diameter of therod, and transverse openings adjacent to the rod, keys respectivelysecuring the blocks in position upon the rod, and shear membersextending through the transverse openings in the blocks and whollysupported thereby exterior of said rod, substantially as set forth.

10. In a reinforced concrete structure, the combination with a body ofconcrete, of a tension rod of substantially uniform crosssectionlongitudinally embedded therein, a plurality of relatively massive castanchorage blocks keyed upon said rod; the same being provided withlongitudinal bores for receiving the rod andtransverse passagespositioned above or beyond said rod, and shear members inserted Withinsaid openings in the blocks and keyed to the rod solely through thebodies of said blocks, substantially as set forth.
